Nicole Richie regrets her ''virgin'' tattoo.

The 32-year-old reality TV star - who has children Harlow, six, and Sparrow, four, with husband Joel Madden - got the inking on her right wrist when she was just 16 years old but now thinks it looks ''embarrassing and desperate''.

She said: ''See this tattoo? It says 'virgin,' you guys. It's embarrassing and desperate.

''Now, I am a Virgo so when I was 16 I thought, 'Ooh I'm going to be different and I'm going to put virgin, because the Virgin is the sign for Virgo.''

Nicole - who was born in California - went on to joke she had considered ways to modify the tattoo, but doesn't think they'd be very convincing.

She told E! News: ''I'd add an I and an A and say I'm from Virginia, but I just don't think people are going to believe me. So I'm just stuck.''

Meanwhile, Nicole is an avid user of Twitter and can't believe some of the ''insane'' responses she gets on social media, particularly as she thinks it is important to be careful about what gets posted.

She said: ''Whether its Twitter or the Internet or the world, you have to be accountable for your words - and you have to be careful with your words, because you can't take them back and that's what you're putting out into the world.

''You've got to be careful with your thoughts and your words.''
